Book excerpt: How do our brains allow us to recognize objects and locate them accurately in space, use mental imagery to remember yesterday's breakfast, read, understand speech, learn to dance, and recall a new telephone number? Recent breakthroughs in brain scanning and computing techniques have allowed researchers to plumb the secrets of the healthy brain's operation; simultaneously, much new information has been learned about the nature and causes of neuropsychological deficits in animals and humans following various sorts of brain damage in different locations. In this first comprehensive, integrated, and accessible overview of recent insights into how the brain gives rise to mental activity, the authors explain the fundamental concepts behind and the key discoveries that draw on neural network computer models, brain scans, and behavioral studies. Drawing on this analysis, the authors also present an intriguing theory of consciousness. In addition, this paperback edition contains an epilogue in which the authors discuss the latest research on emotion and cognition and present new information on working memory.
